Seems like Spring is here

Here are practical, effective ways to cut your air conditioning cooling costs and clean your air conditioner properly. Warmer Temperatures are with us and Summer is around the corner. During a home inspection we will usually run the HVAC system and report on any issues found. However you can reduce your bills by 10-30% depending on your setup, home, and usage.

Ways to Cut Cooling Costs

Make your AC run less often and more efficiently by reducing heat gain, improving airflow, and optimizing settings.

  1. Optimize your thermostat Set it as high as comfortably possible (e.g., 78°F when home, higher when away). Every degree higher can save 3-5% on cooling costs. Use a programmable or smart thermostat to automatically raise temps when you're out or asleep—many save $100+ per year.

  2. Use fans strategically Run ceiling fans (set to counterclockwise in summer) or portable fans to create a wind-chill effect. This lets you raise the thermostat 2-4°F without feeling warmer, potentially cutting costs by up to 14%. Fans use far less energy than AC.

  3. Block heat from entering your home Close blinds, curtains, or shades on south- and west-facing windows during the day to prevent solar heat gain. Consider low-E window film, awnings, or planting shade trees long-term. Seal air leaks around windows, doors, and ducts with caulk or weatherstripping—can improve efficiency by up to 20%.

  4. Maintain your AC system regularly Dirty filters, coils, or ducts force the system to work harder. Change/replace air filters monthly (or as needed), and schedule annual professional tune-ups. This alone can boost efficiency significantly.

  5. Other quick wins

    • Avoid using heat-generating appliances (oven, dryer) during peak heat hours.

    • Switch to LED bulbs (they produce less heat than incandescents).

    • Insulate your home better if possible (attic, walls).

    • For window units: ensure seals are tight and clean them regularly.

Cleaning Your Air Conditioner

Regular cleaning improves efficiency (dirty coils/filters can increase energy use by 10-30%), airflow, and indoor air quality. Safety first: Always turn off power at the breaker before starting.

For Central AC Systems (Outdoor Condenser + Indoor Evaporator)

  • Clean or replace the air filter monthly during cooling season (easy DIY—slide out, vacuum, or replace).

  • Outdoor condenser unit (the big box outside):

    • Clear debris (leaves, grass) from around it.

    • Remove the top grille (check your manual).

    • Gently vacuum or brush loose dirt from coils/fins.

    • Spray with a garden hose (low pressure from inside out to avoid bending fins) or use AC coil cleaner foam (follow product instructions—apply, let sit, rinse if needed).

    • Straighten bent fins with a fin comb if damaged.

    • Clean the condensate drain line monthly: pour 1 cup white vinegar down it to prevent clogs/algae.

  • Indoor evaporator coil (inside air handler—often in attic/basement): This is trickier—use foam coil cleaner (no-rinse types exist), but many pros recommend professional cleaning yearly for deep results.

For Window or Portable AC Units

  • Unplug the unit.

  • Remove the front panel/filter—wash with mild soap/water or vacuum.

  • Clean coils gently with a soft brush or coil cleaner + low-pressure hose (outside if possible).

  • Wipe interior parts and ensure the drain pan is empty/clean.

Do a basic clean 1-2 times per season; deeper cleans (especially coils) benefit from pros if you're unsure.

If your AC is old or inefficient, consider upgrading to an ENERGY STAR-certified model for bigger long-term savings. Start with the low-effort items like thermostat tweaks and filter changes—you'll likely notice lower bills quickly!
